Abstract
A control system for a multi-stage compressor. The control system includes an AC line voltage source, a variable-voltage variable-frequency drive, and a processor. The AC line voltage source is configured to operate the multi-stage compressor. The variable-voltage variable-frequency drive is coupled to the AC line voltage source and is configured to operate the multi-stage compressor at a variable speed. The processor is coupled to the AC line voltage source and the variable-voltage variable-frequency drive, and is configured to alternatively coupled the AC line voltage source and the variable-voltage variable-frequency drive to the multi-stage compressor to operate the multi-stage compressor. The processor is further configured to transmit a capacity control signal to the multi-stage compressor. The capacity control signal is instructive to operate the multi-stage compressor in one of a high-capacity setting and a low-capacity setting.
